My English is very bad but I try to explain
I am a novice Builder who maybe makes really stupid inquires bur I’ am stuck.
I want to build a accordion like this: https://shop.grootsgedrukt.nl/Briefpapier
Now I’m all made this so far that I have this: http://www.iddruk.nl/shop/drukwerk/briefpapier/
but I cannot get it working to link from one to the other
I mean from the one to the other tab
t seems to me very simple but I don’t find the solution

The plugin itself has plenty of options to help you customize the accordion right out of the box which makes integration into any theme a breeze. The author appears to be attentive and the support is great even for the free version ( as there is a premium version too which I recommend ). It doesn’t seem like a one and done plugin and will be around for awhile.
